Handling Procedures and Equipment: IRRITANT.
Workers using this chemical should be thoroughly trained in
its hazards and its safe use, and should wear appropriate
protective equipment and clothing. Use routine safe han-
dling procedures. Use the smallest amount possible for the
purpose, in a designated area with adequate ventilation.
Keep work area free from extraneous materials. Do not get
in eyes, on skin, or on clothing. Avoid breathing mist. Wash
thoroughly after handling.
Storage Requirements: Store in cool, dry, well-ventilated
area, out of direct sunlight, and away from heat or ignition
sources and incompatible materials. Keep containers tightly
closed. Protect from damage and freezing.
FIRST AID MEASURES
Specific Measures:
Eyes: Flush eyes thoroughly with gently running water for
ten to fifteen (10-15) minutes, holding eyelids open while
flushing. Take care not to flush contaminated water into un-
affected eye. Get medical attention.
Skin: Remove contaminated clothing, including watches,
rings, belts, and shoes. Wash skin with plenty of running
water for five to ten (5-10) minutes, or until no trace of
chemical remains. If irritation develops get medical atten-
tion.
Inhalation: Remove to fresh air. Give oxygen and get
medical attention for any breathing difficulty.
Ingestion: If the victim is alert and not convulsing, rinse
mouth thoroughly with water and give 2 to 4 glasses of wa-
ter to drink to dilute. Get medical attention.
